A petcock |69 is` 55 This is adivisional application divided from co-pending application, Serial No.61,982, led February l, 1936.

Our invention relates, in general, to dispensing .I devices and moreparticularly to devices for pumping lubricating oils and greases out oftheir original container, and conducting the oil and grease directlyfrom the original container to the parts to be lubricated, and also forholding Figure 2, shows the device illustrated -in Figure 1 with thecompartment in raised position;

Figure 3 represents a form of our device in which the cover and pump israised by compressed air or other iiuid under pressure, the 5compartment remaining in lowered position; and

Figure 4 showsl a partial view of the form of device shown in Figures 1and 2, but with a different means provided for introducing thecommounted on the exhaust pipe 68 so that when the petcock is turned inone direction, the exhaust pipe |68 is closed and when turned in anotherdirection, the exhaust pipe |68 is opened.

In operation, in order to raise the compartment I3 and to insert orwithdraw the container 8| from under the compartment, air from a sourceof compressed air is inserted through the valve I 1|. When thecompartment is to be raised, thepetcock |69 is placed in a closedposition so that the air will not escape through the exhaust pipe |68.This compressed air introduced into the tops of the cylinders |65 causesrelative movement between the walls of the cylinders |65 andl cylinders|65, which gives a smooth and gradualoperation.

In order to prevent the wobbling of the piston stem within the walls ofthe cylinders |65, especially when in a raised position, we provide theguide washers |62, which being mounted part way down from the piston|64, act as a brace. Secured in the bottom of the cylinders |65 are thewasher blocks |13 which act to cushion the striking of the guide washers|62-upon the bottom of the cylinder wall. The guide -Washers |62, inengaging the blocks |13, prevent the cylinders |65 from rising beyondthe position permitted by reason of the guide washers |62 engaging withthe blocks |13.

In Figure 2, the same device as was shown in Figure 1 is illustrated,but shows the compartment in a raised position. When in this position,the inlet member 49 and end 50 of the pump I6 are raised up out of theopening 82 in the container 8| which sets below the raised' compartment.In this manner the original container" 8| may be moved sidewards on andolf the base II. As is illustrated, the action of the compressed air hasraised the cylinders |65 and caused the block washers |13 inserted inthe bottom of the cylinders |65 to engage the guide washer |62.

When it is desired to lower the compartment again, it is necessary topermit the compressed air in the upper. portion of the cylinders |65 toescape through the exhaust pipe |68 and the petcock |69 by turning thepetcock |69, thus exhausting the compressed air and permitting thecylinders |65 to be lowered. After the exhaustion of the compressed air,the device again assumes the position shown in Figure 1. In Figure 1land Figure 2, the compartment and the cover are permanently joinedtogether.

In Figure 3, we show a modied form of the utilizing of compressed airfor the raising of the inlet member out of the original container. Inthis form, the cover I5 rises up oi the top of the compartment I3 andthe sides of the compartment |3 are securely fastened to the base and adoor I4 is provided on one side of the compartment I3 permitting theinsertion and withdrawal of the original container" through the side ofthe compartment I3. In this form shown in Figure 3, the compartment I3remains secured to the base II, but the cover I5 is raised by means ofcompressed air. In order to provide a brace for the top of the cylinderto engage the cover, we provide angle members |14 which `are suitablyengaged by bolts or welding to the top of the cover I5. The upperportion of each o1' the cylinders |65 is provided with a shoulder |15adapted to engage respectively the lower surface of the angle members14. The shoulders |15 are welded or otherwise secured to the anglemembers |14. In this way, the cylinders 65 are rigidly secured to thecover I5. In other particulars, the construction is similar to thatshown in Figures 1 and 2. It is readily seen that the operation is thesame, except that the action of the compressed air upon the cylindersand the pistons causes the cylinders to rise, which lifts only the coverI5 and the pump and inlet member instead of raising the wholecompartment.

In Figure 4, we illustrate a modification of the device shown in Figures1 and 2. In this modification instead of manually applying a hoseleading from a supply of compressed air to the pipe leading to thecylinders, the air supply to the pump is utilized. As shown in Figure 4,a pipe |19 leads from a source of compressed air and is directed to themultiple Valve through the L-shaped opening |18 in the valve |80. Byturning the handle |11, the L-shaped opening in the valve |80 ispositioned so that the open ends of the L-shaped opening Willcommunicate with any two of the adjoining pipes, the pipe |19, the pipe|16 to the pump, the exhaust pipe |8I, and the pipe |10 to thecylinders. When the lifting mechanism is to be operated and air' is tobe introduced into the cylinders 65, then the valve |80 is adjusted sothat the compressed air from the pipe |19 is conducted through the valve|80 and into the pipe |10 to the cylinders |85. After the compartmenthas been raised, and it is desired to exhaust the air in the cylinders|65, the valve |80 is adjusted so that the compressed air in thecylinders |65 is let out through the pipe |18 through the valve |80 andout through the exhaust pipe |8I. In this way, the turning of the handle|11 of the valve |80 will operate either the pump, o r the liftingmechanism so as to raise or lower the compartment I3.

It can be seen that the use of compressed air or other Icompressiblefluid may be utilized for easy raising and lowering of the inlet member49 in and out of the original container 8| and providing' an easy andsimple manner of changing its position relative to the compartment I3.When the modication shown in Figures 1 and 2 is used, the originalcontainer 8| is moved sidewards under the compartment when raised. Whenthe modification shown in Figure 3 is used, the original container" 8|is put through the side of the compartment I3 by opening the door I4 andby raising the inlet member 49 upward so as not to hinder the sidewardmove of the original container 8|.

The illustrations shown are especially adapted for use in dispensinggrease, oil, or other lubricant capable of being pumped or forcedthrough a conduit. However, it isl to be understood that this device maybe used for dispensing any fluid capable of being pumped or forcedthrough a conduit regardless of itsviscosity.

The great advantage resulting from the use of our invention is apparentfrom an inspection of this device. For examp1e,-when our device is usedin dispensing grease for lubricating automobiles, the grease need not betaken out of the original container and placed in another container, aswould ordinarily be done. By using our device, the grease may betransmitted directly Although we have described our invention with l acertain degree of particularity, it is understood that the presentdisclosure has been made only by way of example and that numerouschanges in the details of construction and the combination andarrangement of parts may be resorted to without departing from thespirit and the scope of the invention as hereinafter claimed.
